Protective system with parallel diode arrangement to cause pulse stretching thus allowing sufficient relay current

Claim 1

IN A SYSTEM FOR AMPLIFYING THE ENERGY LEVEL OF PULSES OF ELECTRICAL ENERGY, THE COMBINATION COMPRISING: A FIRST TRANSISTOR AND A SECOND TRANSISTOR, EACH OF SAID TRANSISTORS HAVING AN INPUT ELECTRODE, AN OUTPUT ELECTRODE, AND A COMMON ELECTRODE, EACH OF SAID TRANSISTORS HAVING AN ALTERNATING CURRENT INPUT CIRCUIT BETWEEN ITS RESPECTIVE INPUT AND COMMON ELECTRODES AND AN ALTERNATING CURRENT OUTPUT CIRCUIT BETWEEN ITS RESPECTIVE OUTPUT AND COMMON ELECTRODES; MEANS SUPPLYING SAID PULSES TO THE ALTERNATING CURRENT INPUT CIRCUIT OF SAID FIRST TRANSISTOR, MEANS COUPLING THE ALTERNATING CURRENT OUTPUT CIRCUIT OF SAID FIRST TRANSISTOR TO THE ALTERNATING CURRENT INPUT CIRCUIT OF SAID SECOND TRANSISTOR; A SOURCE OF DIRECT VOLTAGE; A REACTIVE FEEDBACK BRANCH INCLUDING A SERIES-CONNECTED INDUCTOR AND CONDENSER; MEANS COSCODING THE ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS IN A SERIES LOOP INCLUDING SAID SOURCE AND SAID INDUCTOR OF SAID REACTIVE FEEDBACK BRANCH, SAID CONDENSER BEING CONNECTED BETWEEN THE COMMON ELECTRODE OF SAID FIRST TRANSISTOR AND THE COMMON ELECTRODE OF SAID
